The embodiment of the invention provides a high-voltage loop fault detection method and device, a vehicle and a storage medium, and relates to the technical field of vehicle circuit diagnosis. When the vehicle has an insulation fault, the high-voltage relay pairs are disconnected in sequence; detecting whether the vehicle has an insulation fault or not when the high-voltage relay pair is disconnected each time; and determining an insulation fault source according to the detection result of each disconnection of the high-voltage relay pair. According to the invention, the specific insulation fault source (i.e., the specific insulation fault position) in the high-voltage loop can be positioned, so that the remote automatic diagnosis of the insulation fault of the high-voltage loop can be realized, the detection efficiency of the insulation fault of the high-voltage loop can be improved, the troubleshooting time of the insulation fault can be shortened, and the user experience can be greatly improved.
